I was pretty disapointed in the RC selection in HK. I went to all the spots in Mong Kok too. RC Mart (Dinball) while waaaay out on the other side of town was the only place I really bought anything (They are on the 2nd or 3rd floor of this really ghetto non tourist area and there is no real retail front, but the inside office was nice and the staff were pretty good. I guess it depends on what you are looking for as well.
